what will happen when refregirator door is opened in a closed room.?

Question

While the refregirator is functioning If we opened the door and closed the room airthing, what will happen

Answer 1

a refrigirator works by separating cold and heat, it's call a heat pump and can be used for both heating and cooling of small or large containers. It takes the cold and holds it inside and keeps the heat away. If you open the door of the refrigerator it equalizes the heat. The room temp will not go up or down but you will expend energy and burn your motor out.

Answer 2

Answer: The room's temperature will increase.
Why: The refrigerator will remove thermal energy from the air inside it and pump this energy to the compressor. The compressor squeszes the fluid (doing work) and so puts more energy into the fluid. This now increased thermal energy is released by the condenser into the room, warming the air.
Convection and conduction will eventually mix the air in the room so that the thermal energy goes back inside the refrigerator box. Again it is pumped to the back, again having more thermal energy added by the compressor. Thus the room gets warmer and warmer.
Note that if the door is closed, the compressor will continue to do work for a while, warming the room, but eventually the inside of the refrigerator gets cold enough that an automatic switch shuts off the compressor. This avoids wasting energy and helps keep the room from becoming much warmer, as long as the door is not opened.

Answer 3

When the door is closed the refrigerator moves heat from inside to the outside, so the area inside the refrigerator in maintained at a low temperature.
If we open the door, then for a brief period of time the temperature of the room area in front of the open door will decrease, but eventually the temperature in the room will rise, since the heat produced by the engine of the refrigerator (which, by the way, increases compared to when the door is closed, since we 're overworking the fridge) adds up to the heat already in the room.
So, the bottom line is
YOU CAN'T USE YOUR FRIDGE AS AN AIR-CONDITION!

Answer 4

I'm not sure what you're asking. Do you mean will the refrigerator cool the room? If so, then no--the heat is given off from the coils in the back. So, you have the cooled air coming out the open door, the heat coming off the coils, and the heat from the motor itself running--a net increase in the heat in the room, not cooling.

Of course, if you cut a hole in the wall and stuck the back of the refrigerator out the hole like an air conditioner, that's a different story.

Answer 5

When the room is 100 % thermal isolated, and the fridge door is open,the room temp will raise.
This is because the motor which drive the compressor create extra heat on top of heat removed.
When the door is closed, Heat dissipated by fridge to outside the fridge is higher than the heat extracted from inside fridge.

Answer 6

the room temperature will raised as long as the refrigenarator door is open. actually the principe is same as the air conditioner works...one side is in the room and another side is face another environment to spread out the energy..if the refrigenarator is in the same environment, like u said is in closed room...so the circularitory of the heat is still remain and maintain in that room but is will increased as long as the time.

Answer 7

the room will warm up, the "cold" is created by moving "heat" to the coils. unless the fridge is a perpetual motion machine, the heat created will be greater than the cold created and the room will warm up.

Answer 8

Heating.

Answer 9

your mom will scold you because of the electric bill...

The room will not get cold since the fridge motor is also inside the room.

Answer 10

The fridge and the room will become the same temp. Your electric bill will be sky high.
